      abstract     = {The Jülich Electric Dipole moment Investigation (JEDI)
                      collaboration aims at a direct measurement of the Electric
                      Dipole Moment (EDM) of protons and deuterons using a storage
                      ring. The measurement is based on a polarization
                      measurement. In order to reach highest accuracy, one has to
                      know the exact trajectory through the magnets, especially
                      the quadrupoles, to avoid the influence of magnetic fields
                      on the polarization vector. In this paper, the development
                      of a beam-based alignment technique is described that was
                      developed and implemented at the COoler SYnchrotron (COSY)
                      at Forschungszentrum Jülich. Well aligned quadrupoles
                      permit one to absolutely calibrate the Beam Position
                      Monitors (BPMs). The method is based on the fact that a
                      particle beam, which does not pass through the center of a
                      quadrupole, experiences a deflection. The precision reached
                      by the method is approximately 40μm. Some consequences for
                      the design of a new high precision storage ring for EDM
                      mesasurements are discussed.},
